Application filed April 20, 1918. Serial N 0. 229,780.

To all whom z'tmay concern: Be it known that I, JOHN WAczULA, a subject of the. King of Hungary, (first naturalis zation papers having been obtained,)-and a resident of the city of New York, borough of Manhattan, in thecounty and State of New 'York, have inventedja new and Improved CombinationLathe-Tool, of which the following is a full, clear,'an'd exact description. I j

This inventionrelates to a combination lathe tool and it has for its general objects to provide a, comparatively, simplqinexpem. sive and, useful tool-holding means of such design that a plurality of tools or cutters.

can be used one at a time for enabling a great variety of work to be done.

A more specific objectof the invention is the provision of a tool holder having. a novel form of head whereby a cutter-holding gooseneck, a boring tool or cutters may, be. mounted therein in various positions, --the' clamping means in the head beingsuch thatthe adjustments can be easily effected. l

Another object of the invention is the pros vision of a novel form of gooseneck whereby and quickly a plurality-of cutters can be clamped the'reto, one at a time, by a single-clamping bolt.

With such and other objects in view,.the invention comprises various novel features of construction and arrangement of parts which will be set forthwith particularity in the following description and claims appended hereto.

In the accompanying drawing, which illustrates certain embodiments of the invention and wherein similar characters of reference indicate corresponding parts in all the views,

Figure 1 is a side view showing the gooseneck combination;

Fig. 2 is a plan View thereof with a portion broken away to illustrate details of construction;

Fig. 3 is a vertical section on-the line 3-3, Fig. 2;

Fig. 4: is a side view of the gooseneck separated from the holder and having a cutter clamped therein; v

Fig. 5 is a sectional view on the line 5-'5, Fig. 6, showing a cutter clamped in the holder without the gooseneck;

I Fig. 6 is a side view of Fig. 5, with the head in section; and

, Fig. 7 is a horizontal view showing a boringtool clamped in the holder.

Referring to the drawing, A designates the holder and B the gooseneck. The holder A comprises a bar-like shank 1 having a head 2 disposed slightly at an angle to the length of the shank, viewing the holder in side View, as in Fig. 1. Thishead has a longitudinal slot3 extending-from one side face to the-,other, 'whereby the head is di- .v1ded lnto upper and lower jaws 5 and 6.

Thehead has an opening or passage 7 extending from the-top surface. to the bottom and which is of round cross-section, and the head 1s also provided with a horizontal passage 8 which is coincident with the slot 3; or n other words,.the inner faces of the aws "5, and 6 have recesses struck from a common center so that a. clamping bolt or a boring tool can be gripped betweenth'e jaws.

The'gooseneck B comprises a rectangular head. 9 which has a gooseneck shank 10 connected with the top of the head, and the substantially vertical straight portion 11 of the gooseneck is adapted to enter the opening 7 in the head-of the'toolholder, and the gooseneck is clamped rigidly in place by a bolt 12 which passes through the passage 8 of thetool holder, and this bolt has a recess 13 which constitutes a shoulder for gripping the portion 11 of the gooseneck, to thereby clamp the latter rigidly in place when the nut 14 is tightened. The head 9 ,of the gooseneck attachment hasa horizontal recess 15 in its side to receive a cutter 16, which latter is clamped by a bevel surface or shoulder 17 on the head 18 of a clamping bolt 19 which passes horizontally through the head 9, the top edge 20 of the cutter 16 being formed with a bevel. When the nut 21 -of the bolt 19 is tightened the shoulder 17,

by gripping the top edge of the, cutter 16,

- clamps the latter firmly in the recess 15. Be-

sides the passage 22 extending from side to side of the head 9, the latter also has a hori zontal passage 23 extending from the front to the rear, or transversely to and intersecting the passage 22, such passage 23 serving to receive a cutter 2 1, as shown in Fig. 4..

The bolt 19 has a recess 25 which alines with the passage 23, and one wall of the recess gage the side of the cutter 24 so as to clamp the latter in the passage 23 when the nut 21 of the bolt 19 is tightened, it being understood that in this instance the cutter 16 is detached. In other words, only one cutter is used at a time on the head of the gooseneck.

In order to clam a cutter directly in the holder A, a clamping bolt 27 is inserted in the passage 7 of the head 2, and in this bolt is a passage 28 which alineswith the recess 3 of the head 2, so that the cutter 29 can be inserted between the jaws 5 and 6 and through the opening 28. When the nut 30 of the bolt 27 is tightened the cutter 29 is firmly clamped in position. The cutter 29 can be set at any angle within a range of one hundred and eighty degrees more or less, and to efl'ectively secure the cutter in different positions of adjustment interlocking means are provided between the head 31 of the bolt 27 and the bottom of the head 2 of the holder A. For instance, a projection or tooth 32 may be provided on the head 31 to engage in a recess 33 on the head 2. The tightening of the nut 30 causes the jaws 5 and 6 to firmly grip the cutter 29 to prevent vibration or shifting. The same bolt 27 is utilized when a boring tool 34 is employed in the holder A, as shown in Fig. 7, the shank of the boring tool being inserted through the horizontal opening 8 of the head 2. The bolt 31 has a recess 35 which forms a gripping shoulder to bind the boring tool in the holder A when the nut 30 is tightened. Obviously other tools may be clamped in the holder A or gooseneck B, as necessity demands. I i From the foregoing description taken in connection with the accompanying drawing, the advantages of the construction and method of operation will be readily understood by those skilled in the art'to which the invention appertains, and while I have described the principle of operation, together with the device which I now consider to be 7 the best embodiment thereof, I desire to have passage extending from the top to the bottom and intersecting the slot, a cutter disposed in the slot and adjustable to different angles, and a bolt extending through the passage and having an opening through which the cutter passes, whereby the bolt clamps the cutter in different positions of adjustment.

2. A tool holder comprising a member having a head formed with a slot extending from one side to the other and having a passage extending from the'top to the bottom and intersecting the slot, a cutter disposed in the slot and adjustable to different angles, a bolt extending through the passage and having an opening through which the cutter passes, whereby the bolt clamps the cutter in different positions of adjustment, and means between the bolt and holder for preventing the bolt from turning.

3. In a tool of the class described, a holder including a shank and a head, said head being provided with a passage extending from the top to the bottom and a passage extending from one side to the other, with the passages intersecting and in communication, and also having a slot extending across the head from one side to the other and from one end inwardly, said slot being in the plane of the second-mentioned passage.

4. A combination tool including a head having a slot extending through the front end thereof and through opposite sides of the tool, said slot being adapted to receive a cutter and permit of the latter being adj usted through an angle of approximately 180, said head having also a transverse cutterreceiving passage extending from side to side thereof at said slot to intersect the latter; together with a clamping element exsage and having separate shoulders, of which one is adapted to be engaged with a cutter in the second-mentioned passage of the head and the other is adapted to be engaged with the cutter in the recess.

JOHN WACZULA.
